Setting default image after statement

[rsebastian]

Hey guys,

I've got a question about ImageView. I got a setup for loading all my info via the UIWebView function and it works just fine. I've also build a check to see if there is any connection or not. This also works like it supposed to do. Do only thing i want to do is to show an image if there's no connection.

Here's my code in Viewcontroller.m

-(void)viewDidLoad{
	
	
	NSString *connectionstring = [[NSString alloc] initWithContentsOfURL:[NSURL URLWithString:@"MYWEBSITE"]];
	
	//If there is no connection:
	if([connectionstring length] == 0){
		UIAlertView *alertview = [[UIAlertView alloc] initWithTitle:@"Error" message:@You have to be connected to the internet to use this app" delegate:self cancelButtonTitle:@"Oke" otherButtonTitles:nil];
		[alertview show];
		[alertview release];
		
	//If there is a connection:	
	}else{
		[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"MYWEBSITE"]]];
	}
	
	//Release your string:
	[connectionstring release];	
}

The image i want to add is called "Default.png".

Thanks if you could help!

Ik laad eerst een lokale html-file op deze manier:

	[mainView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"index2.html" ofType:@""]isDirectory:NO]]];

Is the image view in IB or created programmatically?

To add an ImageView programmatically,

CGRect imageViewFrame = CGRectMake( 150.0f, 150.0f, 20.0f, 20.0f);
UIImageView *imageView = [[UIImageView alloc]initWithFrame:imageViewFrame];
[imageView setImage:[UIImage imageNamed:@"Default.png"]];
[self.view addSubview:imageView];

You could declare your imageView in your .h so that you can access it from anywhere in your .m. Also, you could change the CGRectMake(x,y,width,height) values to your requirement.

To add an ImageView using IB.
1. Drop an imageview from the library and place it where you want it to be seen in the view.
2. Create and IBOutlet & connect it to the imageview in IB
3. in your .m, set your image like this

imgViewOutlet.image = [UIImage imageNamed:@"Default.png"];

Hope this helps.

or you can add in IB your imageview with the image and set to hidden, declare in .h the imageview and into your if you can set imagevie.hidden = NO/YES when you need to visualiza/remove the image.
